Application filed November 5, 1925. Serial No. 67,078.

The invention relates to a Vending machine and relates more particularlyto coin controlled vending machines of the selective type wherein thearticles are contained in a plurality of compartments, any one of whichmay be selected by the prospective purchaser and moved into alignment orregistry with a delivery opening normally closed by a sliding door, theopening of said door to permit the article selected to be removed fromthe machine being permitted and controlled by the insertion of a coin ina collection receptacle, thereby permitting the operating handle to beactuated.

An important object of the invention is to provide a coin controlledvending machine of the character described comprising a rotary drumhaving a plurality of radially disposed pockets or compartments adjacentits periphery, said compartments being 1n alignment with correspondingwindows in the drum casing for inspection by prospective purchasers,said drum being freely rotatable by a centrally disposed handle to bringany desired radial compartment into registry with a single dispensingdoor aperture in the drum casing prior to the coin controlled operationof opening the door.

A further object of the invention is to provide a vending machine of thecharacter described so constituted as to cooperate with a coincontrolled mechanism to permit the dispensing door to be opened onlyafter the insertion of the proper coin.

A further object of the invention is to provide a machine of thecharacter described which is incapable of actuation except upon theinsertion of the proper coin together with means for automaticallyreturning to the purchaser any undesired coin of any size capable ofbeing inserted in the reception slot provided for the purpose.

A further and important object is to provide a vending machine includinga rotary drum having radial article receiving compartments any one ofwhich may be freely moved into registration with a normally closed door,mechanism being provided to permit said drum to be freely rotated only 7while the door is closed. The opening and closing of said door iscontrolled by suitable mechanism which is in turn controlled by theoperating handle to move said door successively to open and closedposition. It is contemplated in this regard that when the door is openthe coin slot is obstructed to prevent the insertion ofa coin therein,said ohstruction being automatically removed when the door is closed.

A further object of the invention is to provide a machine ofthecharactcr described in whichsimple and effective mechanism isprovided to return the opened door to closed position by a reversemovement of the oper ating handle to render the machine in position forasucceeding sale. Vhile said door is open the drum is locked againstrotation in either direction to bring a succeeding compartment intoregistry with the door aperture.

A further object of the invention is to provide machine of the characterdescribed in which the contents of the compartments of the drum may beclearly distinguished and readily selected with a minimum of effort onthe part of the purchaser. I 7 Either letters,

numbers, colors, signs, trademarks or names may be used in conjunctionwith the present invention to designate the contents of the drumpockets. And if desired an index or list of the various articles may beprinted or otherwise displayed on the front of the machine for theconvenience of the purchaser to enable him to bring the desired articleimmediately into registration with the door aperture. It will beunderstood in this regard that the machine is designed to dispensevarious articles of widely varying and unrelated character. For instanceone compartmentmay contain razor blades while another compartment maycontain a tooth brush, while still another compartment may contain anyother desired article. The machine is further designed to dispensesan'dwiches, pie and cake which may be put up in convenient paperwrappers, the particular kind of sandwiches, pie or cake being indicatedon the wrapper for the convenience of the purchaser. The radialcompartments containing the different varieties of articles to be soldmay have tabs or indicia thereon to visibly display to the purchaser thenature of the article contained in each compartment.

A further object of the invention is to provide a vending machine of thecharacter described which may beeconomically manufactured and assembled,with most of the Working parts die-pressed, said parts being capable ofbeing assembled rapidly and providing a machine which is extremelydurable in'its nature, as well as adequately protected against pillageby unscrupulous and unauthorized persons.

Referring to the drawings the machine comprises a support 1 which may bea frame or bracket formed preferably of cast metal. having a central hubportion 2 and radially extending legs or brace members 3. The support 1is provided with a circumferential flange i to which is riveted orotherwise secured a circular housing or wall 5. Preferably integrallyformed with the frame member or support are a plurality of cast metalbosses 6, one of which may be formed at the outer end of each of theradially extending brace members or legs 3, and said boss portions arecentrally apertured to have rigidly secured therein a'correspondingnumber of forwardly extending bars or bracing elements 7. The latterproject forwardly of the circumferential wall 5 and are formed withreduced for ward extensions 8 having enlarged headed portions 8 for apurpose to be described. The radially extending legs 3 are preferablyprovided on their rear faces with integrally formed cast metalbossportions 9 which are centrally apertured as at 10 and by means ofwhich are frame member or support 1 may be removably secured against,the wall or counter or any desired location for the machine. The hubportion 2 of the frame member 1 is centrally apertured to have rigidlysecured therein a forwardly projecting central hollow stud shaft 11..One of the forwardly projecting members 8 on the ends of the radiallyextending legs 3is or maybe provided with an upwardly projectingapertured locking lug 12 which may be permanently secured to the armmember 8 as by rivets or by any desired securing means.

The rotary drum or container 13 consists of arear wall 1 1 centrallyapertured as at 15 for the projection therethrough of the central studshaft 11 of the frame member 1. The drum comprises further an outerperipheral wall 16, an intermediate peripheral wall 17 and a depressedoutwardly flanged front wall 18 to which the intermediate peripheralwall 17 is soldered or otherwise secured. The space between thedescribed outer and intermediate peripheral walls 16 and 17 is providedwith a plurality of radially extending partition walls 19 of any desirednumber, forming radial compartments 19 and which partitions serve toreinforce and space the said peripheral walls; the radially extendingwalls being secured to the inner and outer peripheral walls bydownturned ears or lugs 20 extending through corresponding slits orapertures in the inner and outer peripheral walls. V v

The depressed front wall is provided with an enlarged central aperture21 corresponding to and in horizontal alignment with the centralaperture 15 in the rear wall 14 of the drum. Means for providing a rigidrotary support for the drum are provided in the nature of aspider member22 having radially extending legs 23 provided with centrally aperturedbosses 24 at their ends. The spider member is further provided with aninwardly extending preferably integral hub portion 25 adapted to projectthrough the central aperture 21 in the depressed front wall 18 of thedrum. \Vhen the device is assembled the apertured ends of the radiallyprojecting legs of the spider member are designed to coincide with acorresponding number of apertures in the depressed front wall of thedrum, a suitable threaded nut 26 being welded to the rear side of thefront wall 18 so that the spider may be rigidly secured to said frontwall by means of screws 27 or other fastening means. A flat gear 28having peripheral teeth 29 is provided and having countersunk apertures30 near its periphery,'which latter coincide with the apertured legs ofthe spider member 22 to permit the gear to be rigidly secured to thedrum with the spider, by means of the described screws 27 or otherfastening means. The gear 28 is provided with a central aperture 31 anda second pair of diametrically opposed apertures 32 adapted to receivecorresponding projections 33 formed on the spider member 22, and whicharrangement insures that the gear 28 can only be assembled on the spiderand drum in a single definite predetermined position. The fiat gear 28is further provided on its forward side with a pawl 34 constituted of abell crank lever and pivoted at 35 to the gear and having one endthereof normally pressed in contact against a stop 36 on said gear bymeans of a coil spring 37 secured to said pawl and having its other endsecured to a projection 38 on said gear. This arrangement presents theopposite end 39 of the pawl in a certain predetermined position withrespect to the central aperture 31 in said gear, and the pawl may beswung on its pivot against the tension of the coil spring 37 underconditions to be described during the operation of the machine.

The drum 13 is designed to be housed within the peripheral wall 5 of theframe 1 and the central hollow stud 11 of said frame is adapted toproject through the centrally opposedapertures in the rear and frontwalls of the drum and through a central aperture 40 in the spider member22 to provide a journal bearing support for the free rotation of thedrum on the frame 1. The hubportion 2 of the frame 1 provides anabutment to limit the inward movement of the drum 13 on the centralhollow spindle 11 of the frame 1.

The machine further comprises a front casing member .41 having aninwardly projecting preferably integrally formed peripheral flange 42and a plurality of outwardly pro jecting integrally formed ears 43 whichare suitably apertured as at 44 to receive the headed extensions 8 ofthe forwardly projecting arms 7 secured to the periphery of the frame 1.The construction of the apertures in the ears 43 of the casing is suchthat when the later is assembled on the frame to house the drum thecasing is secured in position by a short rotary movement of the laterwhich locks the headed extensions 8* in the reduced portions of theapertures 44'. One of the ears may be apertured to correspond with theapertured lug 12 secured on one of the forwardly projecting arms of theframe. The machine is locked in assembled position by means of thepadlock 45 having its hasp projecting through the aligned apertures ofthe ear 43 of the casing and the lug 12 secured to said frame. Thecasing member 41 which is preferably of cast metal, is provided with adepressed door receiving por tion 46 apertured as at 47 to provide adoor opening. The door aperture is designed to be normally closed bymeans of a sliding door 48 constituted of a door frame 49 having atransparent panel carried thereby. The door frame terminates in adepending extension 50 pivoted at 51 to the upper end of a main dooroperating lever 52, the later being pivotally secured as at 53 to theinner face of the casing. The main door operating lever is provided withan elongated recess 54in which is seated for limited lateral movement apin or projection 55 on the lower end of the depending extension 50 ofthe door frame 49. Through the actuation of mechanism to be hereinafterdescribed the door is designed to be swung on the pivot 53 to open andclosed positions to expose and obstruct the door aperture 47 in thecasing. Suitable guides 56 and 57 are provided and are secured to thecasing by screws or fastening means 58 and 59 threaded into suitableprojections 60 and 61 preferably formed integrally with the inner faceof the casing. The upper guide member 56 is elongated and olfset toassist in maintaining in position one or more circular packing sections62 to be described. The construction of the door lever is such thatlimited pivotal or swinging movement of the door and its extensions 50relative to the main door operating lever 52, is obtained, therebycushioning the door and insuring against possible damage to themechanism of the machine when the door is swung to open and closedposition. This constructionalso permits a snug fit between the topportion of the door frame and the inner peripheral flange 42 of thecasing. The casing is further provided with a pluralitv of radiallydisposed window apertures '63 corresponding in number to the radialcompartments 19 of the drum. The window apertures may be-elosed bymeans'of glass sections fitted between radially extending integrallyformed webs 64 on the inner face of the eas-' ing; the outer edges ofthe glass sections may be further secured in place by means'of aperipheral inturned flange (55 secured to the inner peripheral wall ofthe casing. The inner ends of the glass sections are or may be securedin place by one or moreof the circular packing members 62 formed ofrubber or 3 or closed position.

fabric covered wire, and fitting against the outer faces of a pluralityof projections 66 integrally formed on the inner face of the casing, andthe packing members are secured in place by a corresponding number ofclips 67 secured as by screws 68 to said integrally formed projections.

A coin control housing 69 is preferably i11- te rally formed on thefront face of thecasing and having an apertured boss portion 70 for theprojection through said casing and said coin control housing of acentral oper ating shaft 71 having an operating handle 72 rigidlysecured on the front end of said shaft. The coin control housing 69 isprovided with a removable cover portion 73 having a centrally disposedcoin slot 74 and the cover portion is further provided at each end witha depending spring leg 75 apertured at their lower ends to receivetherethrough corresponding locking projections 76 formed on the casingon the inner opposed walls of the coin control housing. The coverportion 78 is further provided with a sliding member 77 having anelongated aperture 78 to receive a pair of aligned projections 79 on thecover portion, and the slide member is further provided with a dependingrecessed portion 80 on an opposed portion or tab 81 to cooperate withthe coin slot 74 in said cover. The re cessed portion of the slidingmember is designed to cooperate with the door of the machine toalternately obstruct or clear the coin slot according to whether thedoor is in open The cover portion is further positioned on the top ofthe coin control housing by means of opposed projections 82 formed onthe housing and which are designed to' enter corresponding apertures 83in the cover portion. It will be apparent from the foregoing that springlocking means are provided for the cover of the coin control housing bymeans of which the former is normally locked in position by thedepending spring legs 75, the cover however may be removed by releasingthe spring legs from their projections on the interior of the easing,thereby exposing to View for repair or replacement, the interior of thecoin control housing. The construction described permits the coincontrol to be easily accessible to authorized persons and renders itunnecessary to completely dismantle the machine in the event thatrepairs are necessary or that the coin slot and control mechanismbecomes obstructed by a spurious coin.

The coin receptacle consists of a box 84 adapted to fit against thelower side of the coin control housing to receive the coins passingthrough the coin control during the operation of the machine. Means areprovided to securely lock the coin receptacle in position on thefront ofthe machine, to permit the same to be removed and replacedby an emptyreceptacle by anauthorized person by means of the single key lockindicated at 85. These means consist of a cast rib or projection 86 onthe front of the casing corresponding in shape but slightly larger thanthe periphery of the coin receptacle. The latter is adapted to nest orfit within said rib and the coin receptacle s4. is provided withpreferably integrally formed projections 87 adapted to register withcorresponding apertures or cutaway portions 88 in the casin The coinreceptacle is locked in position by turning the key in the lock 85, andis removed in a like manner, The cooperation of the projections 87 withthe recesses 88 prevents the coin receptacle from being tilted orotherwise removed from within the enclosing rib 86 by means other thanby turning the key in the provided lock 85. The coin control housing isfurther provided with an aperture 89 communicating with the coin slot-74in the top of the housing and by means of which improper or spuriouscoins are returned to the purchaser without affecting the operation ofthe machine.

If desired each radialcompartment of the drum may be provided with a tab133 on which may be displayed the kind of article within thecompartment, said tabs being visiblc through the transparent windows ofthe machine casing for the convenience of the purchasers. The tabs 133may be suit-ably hinged within the several compartments so as not toobstruct the removal or insertion of an article within said compartment.

The coin controlled mechanism contained within the housing 69 of thecasing, may be of any desired or suitable type andis designed to beoperated by the main central shaft 71 and the operating handle 72 keyedto the outer end of said shaft. A coin mechanism may be utilized such asis fully described in my co-pending application, Serial No. 464,7 7 0,filed April 27, 1921 for coin controlled device. An examination of thecoin controlled mechanism described in my said co-pending applicationwill aid in a complete understanding of the present machine.

A drum locking lever 90 is pivoted at 91 to a suitable hub portion onthe inner face of the casing and having its outer end normallymaintained against a stop projection 92 secured to the casing, by meansof a coil spring 93 secured at one end to said locking lever and havingits other end secured to a pin or projection 94 on the inner face of thecasing. The locking lever 90 is provided with an integral upstanding arm95 having an inwardly extending locking projection 96 thereon, the

latter serving as a journal support for a friction roller 97 looselymounted on said projection. The construction is such that when thecasing is assembled over thedrum the locking projection 96 of thelocking lever 90 engages the peripheral teeth 29 of the gear 28 securedto the front wall 18 of the drum.

When the drum is rotated in one direction in a manner to be hereinafterdescribed to bring the desired compartment in registry with the dooraperture of the casing, the projection 96 is permitted to ride over theperipheral teeth of the gear wheel by reason of the yielding nature ofthe coil sprin 93 secured to the outer end of the drum locking lever. Anotch or recess 98 is provided near one end of the drum locking lever topermit the yielding engagement of the locking projection with the gearwheel only when the door is in closed position.

The door is normally maintained in closed position by means of a coilspring 99 engaging at one end an inwardly extending projection or lug100 on the main door operating lever 52 said spring being secured at itsother end to a lug or projection 101 on one arm of a rocking lever 102pivoted at 103 to the inner face of the casing. The door lever and doorare normally securely locked in closed position against movement bymeans of a locking lever 104 pivoted at 105 to the main door operatinglever said lever 101 having its free end normally held by means of aspring 106 in contact with or adjacent to a lug or projection 107preferably integrally formed on the inner face of the casing. The lowerend of the tension spring 106 is secured to a projection 108 also formedon the inner face of the casing. The free end of the pivoted lever 104.-is further provided with a plurality of notches or recesses 109 designedfor engagement with the projection107 on the casing. An inturned lug orprojection 110 on the main door operating lever 52 serves as a stop tolimit the inward movement of the pivoted lever 104 under the tension ofthe coil spring 106.

\Vhen the door is moved to open position upon the actuation of themachine, means are provided to lock said door in open position againstthe tension of the coil spring 99 the tendency of which is to close thedoor. These means comprise a rounded shoulder or notch 111 on the end ofone of the arms 102' of the rocking lever 102 which shoulder drops downand engages a cooperating lug or projection 112 on the main dooroperating lever 52 when the door is moved to open position. The arm 102of the rocking lever 102 is further provided with an inwardly extendinglug or projection 113 the engagement of which causes the door to beautomatically returned to closed position in a manner to be described.

The coin controlled mechanism within the h ousiug 69 includes a doublefaced rotary cam The loosely mounted tubular sleeve is dis-' posedimmediately adjacent the disk member 115 and is provided on one end witha pair of diametrically opposed peripheral notches or recesses 121adapted to be engaged by one end of a locking pawl 122 pivoted at 123 tothe disk member, the other end of said pawl being yieldingly maintainedin contact with the periphery of said tubular sleeve by means of a coilspring 124 secured to said pawl and secured at its other end to aprojection 125 which may be integrally formed with the loosely mounteddisk member 115. The other end of the loosely mounted tubular sleevemember 118 is provided with a cut-away portion 126 extending forsubstantially one half of the circumference of said member and forming aprojecting shoulder 127 adapted to be engaged by the spring pressed pawl34 pivotally mounted on the gear wheel 28 secured to the drum.

Vhen the machine is to be actuated, and assuming the door to be closed,the operator first visually selects through the windows 63, the articlewhich he desires and then rotates the operating handle to the left or ina counter-clockwise direction as viewed in Fig. 1. In this direction theshoulder 127 on the tubular sleeve 118 engages the free end of the pawl34 carried by the drum, and freely rotates the latter on its journalsupport 11 until the desired compartment is aligned with the dooraperture, at this time obstructed by the closed door 48. During thisreverse rotation in a counter-clockwise direction of the drum to selectthe article to be purchased, the projection 96 of drum locking lever 90is permitted to ride over the peripheral teeth of the gear wheel carriedby the drum by reason of the yielding nature of the spring 93. The notch98 in the drum locking lever permits the latter to be intermittentlyelevated by the outward pressure of the gear wheel teeth, said notchbeing adapted to receive therein the projection 100 of the dooroperating lever 52, which projection in the absence of said notch wouldprevent the lever 90 from being elevated and consequently prevent thedrum from being rotated to select the compartment desired. The propercoin is inserted in the slot 7 4: of the coin control housing and theoperating handle secured to the main central shaft 71 is now turned tothe right or in clockwise direction as viewed in Fig. 1. Failure toinsert a coin results in the inabilit to rotate the operatinghandle 72and sha t 71 by reason of the engagement of the locking pawl 122 carriedby the disk member 115 with one of the peripheral recesses 121 of thetubularmember 118 looselyicarried by said shaft, it being understoodthat the tubular member one of the peripheral notches 121 carried by'the tubular member after the latter is engaged and rotated by thetransverse rod mem her 120. The insertion of the coin permits the diskmember 115 to be thereafter rotated until the lowermost roller 117carried by said disk engages the curved cam surface 128 of the doorlocking lever 104 pivoted to the main door operating lever 52. 'As theroller 117 moves upwardly against the said cam surface, the lockinglever 104.- is moved outwardly against-the tension of the spring 106'and out of engagement with the locking projection 107 on the casing.Immediately thereafter the said roller 117 engages a correspondingcurved cam surface 129 on the main door operating lever 52 therebyresulting in said lever and the door carried thereby being moved to openposition against the tension of coil spring 99. This opening movement iscontinued by the rotation of the roller 117 until the dependingextension 50 of the door frame engages an integral projection 130 on thecasing, and the continued movement of the door lever results in the doorand its extension frame 50 being swung quickly to open position on theauxiliary pivot 51. At precisely this moment the rounded shoulder 111 ofrocking lever 102 engages the projection 112 ,on the door operatinglever 52 thereby locking the door in open position. The purchaser maynow obtain access through the open door to the contents of thecompartment of the drum which he has moved into registrywith the dooraperture. In this position of the machine and with the door open it willbe observed that the projection 100 of the door operating lever 52 isdisposed above and immediately adjacent the upper edge of the drumlocking lever 90. This arrangement, due to the movement of projection100 relative to the recess 98 in the drum locking lever, prevents thelatter from being elevated to move a succeeding pocket into registrywith :the door opening, and the drum is therefore securely locked by thelocking projection 96 against movement in either direction. This is truewhile the door is open and also while the door is being moved to openand to closed position. It is only when the door-is closed and locked bylever 104 in closed position, that the drum 13 may be rotated, and thisis due to the relation between projection 100 on the door operatinglever and recess 98 in drum locking lever 90. These elements are only inalignment to permit yielding upward movement of the drum locking leverwhen the door is in closed position.

scrupulous persons.

l/Vhen the purchaser or a succeeding purchaser desires to again operate.the machine it is first necessary to close the door, thereby permittingthe drum to be again rotated to select the contents of its desiredcompartment. The operation of closing the door is effected by a reversemovement of the operating handle in the same manner in which the drum isfreely rotated when the door is closed. The door being open, there is nomovement of the drum for the reasons described, and the adjacent end ofthe transverse rod 120 engages the projecting lug 113 of rocking lever102 as the handle is turned in a reverse direction. Continued movementof the handle through the engagement described lifts rocking lever 102until the rounded portion of its shoulder 111 is brought adjacent theupper portion of the locking projection 112 on the door operating lever52. Thereafter the door is swung suddenly to closed position by thetension of the coil spring 9 which releases the rounded shoulder 111from the projection 112 on the door lever. It will be observed in thisconnection that as main door operating lev-eris moved toward closedposition, the lower end of door carrying member or extension 50 strikesa'second projection 131 integrally formed on the inner face of thecasing, which serves to swing the door frame 49 and door sharply toclosed position on auxiliary pivot 51, relative to the main dooroperating lever. In this manner a relatively small movement of the mainoperating, lever is caused to produce a greater range of movement of thedoor frame and door. This movement also permits the door locking lever104 to be again swung by spring 106 into alignment with the projection107 on the casing, to prevent the door from being again opened exceptonly when the main operating shaft is turned in a clockwise direction toengage the other roller 116 of the loosely mounted disk member 115 withthe curved cam surface of locking lever 104 and main door operatinglever 52. As this operation can only be obtained upon the insertion ofthe proper coin, the machine is effectively locked against pilfering byunauthorized or un- WVhen the main shaft is being rotated in a clockwisedirection to open the door, the pawl 34 carried by the gear wheel 28slips loosely by the shoulder 127 of the tubular sleeve 118 as will beunderstood, thereby resulting in no movement of the drum when theoperating shaft is being turned to open the door. The engagementdescribed of the pawl 34 with the drum only take place when the door isclosed and when the shaft is being rotated in a reverse direction. Therecannot be any rotation of the shaft in a clockwise or forward directionwhen the door is closed except by the insertion of the proper coin, andthis coin can not be inserted in this slot when the door is open becauseof the slidment of the shaft while the drum is locked stationary, toagain swing the door to closed position. The manner of operating themachine by succeeding purchasers is exactly the same manner as has beendescribed above for both opening and closing the door, the opening ofthe latter being permitted only by the insertion of a coin in thecontrol housing slot 74.

Referring to Fig. 10 means are provided to protect the machine againstdamage in the event that the machine becomes temporarily out of order orin the event that unscrupulous persons attempt to operate the machinewithout first inserting the required coin in the coin control housing.The operating handle 72 is frictionally secured by suitable clutchmechanism to the transverse central shaft 71. Diametrically opposedresilient clutch members are carried by the handle and cooperate withthe shaft 71 to permit the latter to be operated ,by the handle 72 afterthe desired coin has been inserted in the machine. As illustrated thehandle 72 is provided with opposed boss portions 185 which are centrallapertured as at 136. The shaft is providec with opposed recesses ordepressions adapted to coincide with the apertures 136. A pin or plunger137 is loosely seated within each aperture 136 and is normally pressedinto engagement with the opposed recesses of the shaft 71 by means of acoil spring 138. The opposite end of each coil spring 138 bears againsta set screw 139 which is threaded into the aperture 136. A lock nut 140is provided and threaded into each aperture 136 to bear against theouter end of the set screw 139. It will be apparent that any desiredtension of the springs 138 may be obtained by removing the lock nuts 140and adjusting the set screws 139. The adjusted ten sion is such that theplunger 137 bears with sufficient force against the shaft 71 to permitthe latter and the handle 72 to be turned as a unit during normaloperation of the machine. Should the machine become damaged or should anattempt be made to operate the same without first inserting the requiredcoin, the plungers 137 will be forced out of their engagement with theshaft 71 against the tension of the springs 138 and the handle 72 willbe rotated independently of and without corresponding movement of theshaft 71. In this manner all of the mechanism of the machine controlledby the shaft 71, is protected against undue damage or breakage duringthe operation of the machine.

As best seen in Fig. 4 means are provided to insure the properpositioning of the disk member 115 with the rollers 116, 117 insubstantial vertical alignment on each actuation of the machine. A lever141 is pivoted at 142 to the casing and is provided at its free end witha roller 143. A tension spring 144 is secured at one end to the lever141 and is secured at its other end as at 145 to the casing.
